APPARATUS FOR TREATING. TEXTILE FABRICS.

Patented June 19, 1906.

' sylvania, have invented certain new and useful Improvements in Apparatus for Treating Textile Fabrics, whereof the following is a specification, reference being had to the accompanying drawings.

It is the generalobject of our invention to provide an apparatus wherein textile fabrics may be saturated with liquid and have the surplus liquid discharged therefrom without removal from the apparatusand without agitating the latter. scribed said apparatus is adapted for subjecting cloth and other textile fabrics towashing, dyeing, carbonizing, and other proc esses, which as hitherto employed have ne- '20 cessitated the removal of the treated fabrics from one apparatus to another to effect the stance,to effect the carbonization of woolen 1 cloth to free it from vegetable matters in the ordinary manner necessitates the following steps: The cloth is saturated with acid liquor in one apparatus, removed therefrom I to a second'apparatus, (a whizzer or centrifugal drier,) to discharge the surplus liquor, then removed to a third apparatus, wherein itis baked at a temperature of from 225 to 230 Fahrenheit, then-removed to a fourth apparatus and saturated with alkaline liquor to neutralize any residue of acid,

then removed to a fifth apparatus and again whizzed, and then removed to a sixth apparatus to-dry it.

As hereinafter described our invention provides a single apparatus wherein fabrics 4o may be subjected to all of the steps'aforesaid without removal or agitation, with the advantages, first, that the fabrics remain in the original smooth condition in which they are made; second, the damages incident to repeated handling are avoided, and, third, that the various effects contemplate may be atric while a closely As hereinafter de- I For in-- novel features of construction and arrangement hereinafter more definitely specified.

In the accompanying drawings, Figure I is a diagrammatic view showing in side elevation an apparatus conveniently embodying our improvements. Fig. II is a left-hand end view of the fabric-treating tank shown in Fig. I. Fig. III is a vertical sectional view' of said treating-tank, taken on'the line III III in Figs. I and IV. Fig. IV is a longitudinal sectional view of said treating-tank, taken on the line IV IV in Fig. II. F1g. V is a longitudinal sectional view similar to Fig. IV, but showing a modified form of treatingtank. Fig.VI is a plan view of the manifo (1 shown in Fig. I. v Fig. VII is a sectional View of the back-pressure valve shown in Fig. I. Fi .VIII is a sectional view of the four-way va ve shown in Fig. Fig. IX is aside elevation' of the four-way-valve plug shown in section in Fig. VIII.

Referring to the form of treating-tank shown in Figs. I, II, III', and IV, the outer shell of the tank 1 is conveniently supported on the standards 2 2 and comprises the stationary-closed head 3 and the open framehead 4, provided with the removable lid 6. Said lid 6 comprises peripheralnotches7, adapted to receive the swing-bolts 8, whose T-heads 9 are pivoted in the lugs 10 on the head-frame 4, and whose shanks are screwthreaded, as indicated'at 13,.to receive the wing-nuts 14, by which said lid 6 is normally secured in closed position.

As shown in Fig. III, the tank 1 is provided upon its opposite sides with angle-flanged rails 16, arranged for engagement with the truck-wheels 17 18,.which are supported in suitable bearings in the truck-frame 20. The flange 21 on said truck-frame20, as shown in Fig. IV, engages in the notch 22 in the trunnion 23 of the foraminous drum- 24, which is provided at its opposite extremity with the trunnion 25 in axial alinement' with the trunnion 23. When removed from said tank 1, said drum 24 serves as a roller upon which a bolt of cloth 27 may be conveniently wound,

TOO

the conduit 31, which latter extends through the bottom of the tank 1 and to the valve-casing 32, where it terminates in the port (Shown in Fig. VIII.) The bottom of said tank 1 is also provided with the conduit 34, which extends to said valve-casing 32 and terminates therein in the port 35, also shown in Fig. VIII. Said valve-casing is provided with valve-ports 36 and 37, respectively opposite to said ports 33 and 35, and the valveplug 38 comprises ducts 39 and 40, arranged to establish communication between the op posite ports 33 36 and 35 37 in the position shown in Fig. VIII. Said plug 38 also comprises the ducts 41 and 42, through which the opposite ports aforesaid are cross-connected when the plug is in the position shown in Fig. IX.

It is the general purpose of the four-Way valve above described and the remainder of the apparatus to supply the tank 1 with fluid for treating the textile material surrounding the drum 24 either by injecting the fluid from the inside of said drum 24 outwardly or in the reverse direction, as hereinafter described.

Referring now to Fig. I and the detail figures upon the same sheet, we provide the ports 36 and 37 in the casing 32 with conduits 45 and 46. (Shown in Fig. I.) The conduit 45 extends to the chamber 47 in the manifoldcasing 48 and is provided intermediate of its length with a stop-valve 49 and by-pass conduits 50 and 51, respectively controlled by stop-valves 52 and 53 upon, respectively, opposite sides of said valve 49, connecting the conduit 45 with a heater 55f Said heater 55 may be of any suitable construction to raise the temperature of the fluid traversing the by-pass conduits 50 and 51. For instance, it may have diaphragms 57 and 58, connected by tubes 59, which extend through a chamber 60 between said diaphragms, provided with an inlet 61 and an outlet 62 for the heating medium-for instance, steam. The conduit 46 extends to the chamber 64 in the manifold-casing 48 and is provided intermediate of its length with the stop-valve 65 and by-pass conduits 66 and 67, respectively controlled by stop-valves 68 and 69 upon respectively opposite sides of said valve 65, connecting the conduit 46 with a cooler 71. Said cooler v71 may be of any suitable construction to lower the temperature of the fluid traversing the by-pass conduits 66 and 67for instance, such as the heater 55, above described, except it comprises an inlet 72 and an outlet 73 for the cooling mediumfor instance, anhydrous ammonia-vapor or cold brine. As shown in Fig. I, said manifoldchambers 47 and 64 are respectively connected by conduits 75 an d 7 6 with fluid-supply tanks 78 and 79, which may, for instance, contain liquid whose level is indicated by the respective dotted lines 80 81, such connection being effected through the valve 77, which is similar in construction to the valve 32 (shown in Fig. VIII) and permits either direct or cross connection of said 111anifoldchambers 47 and 64 with said tanks 78 and 79. The fluid or liquid totreat the textile material within the cylinder 1 may be circulated by a pump or in any convenient manner. However, in Fig. I we show a pipe 83, which maybe connected with any suitable source of compressed air and which comprises branch pipes 84 and 85, respectively controlled by stop-valves 86 and 87 in respective communication with the tanks 78 and 79. Said tanks 78 and 79 are conwniently provided with liquid-inlet pipes 89 and 90, respectively controlled by valves 9]. and 92, and said tanks are also provided with fluid vent-valves 94 and 95.

It is to be understood that the tanks 78 and 79 above described may be used to contain any liquid with which it is desired to treat the fabric in the tank 1, and any desired number of groups of such tanks may be employed in connection with the manifold casing 48. For instance, as indicaied in Fig. V I, the pipe 97 may lead to a supply of alkaline liquor or soapy water. The pipe 98 may lead to a supply of dye liquor. The pipe 75, above described, may lead to a supply of acid liquor. The pipe 99 maylead to a supply of clear water, and the pipe 100 may directly connect said manifold-casing 48 with the source of compressed air.

The apparatus above described may be used for carbonizing a belt of cloth 27, as follows: A supply of acid liquor having been introduced to the tank 78 by the pipe 89, the valve 91, controlling the latter is closed, and the vent-valve 94 being also closed the valve 86 is opened to admit compressed air from the pipe 83. The valve 49 beingopened and the by-pass valves 52 and 53 closed, said acid liquoris forced from the tank 78 through the conduit 75, manifold-chamber 47, and conduit 45, to the valve-casing 32, and the lug 38 being set, as shown in. Fig. IX, said iquor is delivered to the tank 1 through the conduit 34 until the space in said tank 1, ex terior to the cloth 27, is filled therewith Thereupon the plug 38 is rotated in the casing 32 to the position, shown in Fig. VIII, so that the liquor supplied through the conduit 45 is thereafter delivered to the tank 1 through the conduit 31 within the foraminous drum 24, through which it passes to the cloth 27, and after percolating through. the latter circulates with the exterior liquor out through the conduit 34, through the valve-plug 38, (which latter is in the position shown in Fig. V ].II,) to the automatic pressure-regulating valvecasing 101. (Shown in detail in Fig. VII.) The port 102 in said valve-casing 101 is normally closed by the valve 103 under pressure of the weight 104, which latter is adjustable Y Said liquor passes from the manifold-cham- 1 83 through the conduit 100.

ber 64 to the tank 79, whose vent-valve 95 is opened to permit its inflow. The liquor circulated as above described throughthe textile fabric 27 in the tank 1 may be discharged therefrom by compressed air introduced through the tank 7 8 or by compressed air introduced directly from the supply-conduit (Shown'in Fig.

VI.) The compressed air being introduced through the drum 24 passes thence. through the convolutions of the fabric 27,driving ofl the sur lus liquor, which latter is withdrawn throug the conduit 34. The stream of air passing to the tank 1 may be gradually raised in tem erature b opening the by-pass valves 52 and 53 and c oslng' the valve 49, (shown in Fig.- I,) thus causing the air supplied to the tank 1 to traverse the heater 55 until the fabric 27 is baked at a temperature of from 225 to 230 Fahrenheit. Thereafter the by-pass valves 52 and 53 being closed and the valve 49 opened, alkaline liquor may be.

introduced in the manner described with respect to the acid li uor, so as to neutralize any acid residue in t e fabric 27, and by suitable manipulation of the apparatus, as above described, compressed air ma be again introduced to drive off said alka ine liquor from the fabric 27 and to dry the latter.

In order to dye the'fabric 27 above de' scribed,indigo dye may, for instance,be supplied to the manifold 48 through the pipe 98 (indicated in VI) and by manipu ation of the apparatus in a manner similar to that described with reference to the introduction of acid liquor. Said fabric 27 may be saturated with the dye'liquor, which is preferably introducedat atmos heric temperature and gradually raised to t e boiling-point by' bypassing it through the heater 55. (Shown 1n Fig. I.) When thus dyed, the fabric 27 may be freed from the surplus dye liquor by the introduction of com ressed air, as above described, and the continued percolation of air through said fabric serves to both oxidize and set said dye and dry the fabric. i

With the form of drum 24 (shown in Fig. IV) the fabric 27 may be removed after treat- 'ment by removing the lid 6' of the tank 1, dis connectin the flange 29 of .the standard 28 from the ange 30 of the conduit 31, withdrawing said drum 24 with its trunnion 23,

that thefabric 27 maybe reeled off there from.

Although we find it convenient for th manipulation of cloth and similar lengthy materialsuch as warp-threads, &c.to .em-

ploy a drum which may be removed from the tankl, asabove described, we find it convenient for 'carbonizing and dyeing yarns in hanks, hosiery, and similar small articles to provide a tank 1, such as is shown in Fig. V, wherein the stationary foraminous drumshaped diaphragm 105 is surrounded by a second similar diaphragm 106, forming a chamber 107, in which the material to be treated maybe packed. Said chamber 107 is conveniently provided with the lid 108, secured by the nut 109, engaged with the screw-threaded flange 110, which latter is stationary on said drum 105. In this form of our invention the conduit 31 may be permanently connected with the interior of the drum 105 by the conduit 111.

Although we have described a convenient form of treating-tank wherein the compartment for containing the fabric to be treated is a cylindrical vdrum of foraminous diaphragm it is tobe understood thatjwe do not esire to limit ourselves to the particular construction herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of our invention.
